I am having a problem with this homework problem. I have asked my teacher to help but she wont respond for 3 days or so. Anyway, I have gotten this problem wrong and a new one has generated. the answer to the problem was -3.6380 The biggest issue I have with this problem is the end when you must condense everything. I can get it down to -2ln8-2ln7/2ln8-ln7 I just dont know what to make the -2 Is it turned into ln8^-2 or ln8^1/2 I know these are wrong, that is why I need help.

no it wanted the calculator total that was supposed to come to -3.6380 You are supposed to condense the problem down, something like this ln8^-2 - ln7^2/ln8^2 - ln7 only the ^-2 part is wrong, that is were I need help, figuratively speaking you would then do the next part, which is to use all the powers. ln8^-2 would be = ln 0.015625 (wrong I know but I did say figuratively) ln7^2= ln 49then the bottom part of the fraction would beln8^2= ln64ln7 would remain the same. then you would put it all back together and it would look something like this.ln0.015625-ln49/ln64-ln7then you wold take the top and divide the two then do the same with the bottom, and then you would be ready to put it into the calculator. I have no idea what I'm talking about really this is just what I sow on the "helpful" similar problem video that accompanies the homework problem. they pass steps though and those are usually the steps I need.

hmmm..not really sure what you are trying to accomplish here since you already have the answer...but...
